I ran nothing by Federal 115gr through my SR9c for the first several hundred rounds. The only problem I had was two stovepipes in the first couple mags because of limp wristing. My trigger pull smoothed out by about 500 rounds. It was a little gritty at first, and I was convinced I had gotten a bad/abused at the gun store model. Not so, just had to put some rounds through it. It wasn't terrible, just not the silky smooth pull the rental SR9c had. Mine now has that same silky smooth pull.
Be sure and thoroughly clean before you go to the range. Don't forget to pull the striker and clean it and the striker channel too. My Mark I has been feeling neglected since I got the Sr9c.
